[vc_row][vc_column][vc_column_text]Digital Matrix Amplifiers: here’s what’s behind the DMA acronym, a series of three new amplifiers featuring digital matrix, class D power electronics and a very powerful DSP platform. A range of proprietary RCF technologies designed for applications that require high sound quality and ease of installation.
The new DMA series is built on the basis of a large number of RCF technologies, in order to best serve and enhance the characteristics of the controlled speakers. These are class D amplifiers equipped with a powerful DSP platform, which allows the management of inputs and outputs for both routing and equalisation.
Among the processing functions available, the speaker presets, a proprietary algorithm for bass enhancement, FiR filters and environmental equalisation should be underlined. All three models, which we are now going to see in detail, are also characterised by robustness combined with small size and compact structure, thanks to a design with great attention to every detail. This makes RCF’s DMA series products very suitable for a wide range of applications.
A ‘trident’ of models
The new series of RCF amplifiers looks like the strong attack of a football team: a ‘trident’ deployed with the intention of developing the game of the whole team in the best possible way, with particular attention paid to the speakers. Each model has its own salient features: DMA 162 is a 160W two-channel Class D matrix amplifier (2x160W @ 4 ohm or 320W hi-Z), ideal for a wide range of commercial music applications. DMA 82 is always a two-channel Class D matrix amplifier, which however reach 80 W (2×80 W @ 4 ohm or 160 W hi-Z), and is perfect for applications such as small shops, meeting rooms, bars, restaurants, clubs and supermarkets.
Finally, the DMA 162P model is a 160 W two-channel Class D power amplifier, designed as an expansion for the DMA matrix units just described, which is therefore proposed as the central element of the trident we are illustrating. DMA 162P therefore allows to increase the installed power and to implement multi-zone architectures for commercial audio systems. This model, however, works equally well as a stand-alone amplifier thanks to features such as adaptability, control tools and the range of inputs available (1 x 4 channel BUS via RJ-45 and a stereo or RCA line input, alternative to AUX IN on the front panel.)
Robust and simple to set up
Beyond the power differences, all three models are characterised by a series of common properties that make the RCF’s DMA Series particularly compact and versatile. All models can be used both as a desktop unit and installed in a rack, and are simple to configure, an important detail in sound reinforcement systems. Anyone, even without profound technical skills or long experience, is able to proceed with the configuration of the DMA units, which also have different configuration levels. It’s possible to work both from the front panel control interface (particularly simple and intuitive) and through the RDNet management, suitable for complex and large systems (using the appropriate card available as an accessory).
Finally, a series of pre-loaded presets are designed to optimise the performance and equalisation of any RCF speaker, bringing the sound level in any environment to a high standard, without compromise (RCF is a brand that always aims at professional sound quality.) The on-board DSP platform is decidedly powerful and performing, while we have already mentioned the proprietary RCF technologies installed on the three amplifiers of the DMA series, from FiRPHASE, FiR filtering technology, to BASS ENHANCER, a sophisticated algorithm developed to improve the perception of low frequencies without it being to the detriment of the output power. All this for a professional level result, an objective from which RCF never derogates. And with a trident like this, the goal is guaranteed!
